Description

Sodium Decyl Phthalate CAS NO 20259-91-0 is an organometallic salt derived from phthalic acid and decyl alcohol, serving as a versatile intermediate and functional additive. Its primary value lies in its ability to act as a plasticizer, surfactant, or catalyst component, imparting specific properties to polymer systems and formulations. This product is essential for manufacturers in the plastics, coatings, and specialty chemical industries seeking to modify material characteristics such as flexibility, compatibility, or processability.

Application

• As a specialty plasticizer for polyvinyl chloride (PVC) and other polymer resins to enhance flexibility and low-temperature performance.
• As a functional surfactant or emulsifier in industrial cleaning formulations and emulsion polymerization processes.
• As a lubricant additive or viscosity modifier in specialty greases and metalworking fluids.
• As a chemical intermediate in the synthesis of more complex esters, dyes, or pharmaceutical agents.
• As a dispersing agent for pigments and fillers in coating and ink systems.
• In the formulation of adhesives and sealants to improve workability and final product properties.

Quality Control

Our Sodium Decyl Phthalate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity and performance. Certificates of Analysis (COA) documenting key parameters are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality.
